APPARATUS FOR CLEANING STEAM-PIPES.

- SPECIPICATIONforming part of Letters Patent No. 345,434, dated July13, 1886.

' steam pipes and pumps and removing the dirt and sediment in drypipes,&c., and to prevent freezing without taking the pipes apart.

The invention consists in the-combination,

with a boiler-pump and feed-water heater, of a pipe connecting theboiler with the pipe leading from the tank or well to the feedpump, andof a three-way cock uniting the said pipes.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, in which a side view of a boiler, feed-water tank,pump, and heater are shown provided with our improvement.

On the boiler A the dome B is provided, from which the pipe 0 leads tothe pipe E, which connects the feed-water tank F with the pump G, thepipes C and E being connected by athree-way cock, H. The pump G isconnected by a pipe, J, with the feed-water heater K, which in turn isconnected by the pipe D with the boiler. L is a three-way cock, M acheck-valve, and N a waste-pipe. The feed-water is pumped from the tankF through the pipe E and the heater K into 5 the boiler.

To clean the pipe E the threeway cock H is turned in such a manner thatthe dry steam passes through the pipe E and cleans the same.

Whcn the pump G, the pipe J, the heater 40 K, and the pipe D are to becleaned, the threeway cock is turned in such a manner that the dry steampasses through them. The dry steam passing through the pipes cleans themand carries off and blows out all the dirt, 45 smut, and sediment veryrapidly without requiring any of the parts being detached or takenapart.

Having thus described our invention, what We claim as new, and desire tosecure by Let- 5o ters Patent, is

The combination, with a boiler, of the pipe E, connecting the tank orwell with the feedpump and feed-water heater, the pipe 0, connecting theboiler with the pipe E, and the 5 three-way cock H at the connect-ion ofthe pipes O and .13, substantially as herein shown and described.
